You cannot. But you can define another class which contains
a Set object as an attribute and forward all of the messages
to this attribute:
@interface MySet : SwarmObject 
{ id set; ... }
-forward: (SEL) aSelector : (arglist_t) arguments;
...
@end

@implementation MySet
-forward: (SEL) aSelector : (arglist_t) arguments {
  return [ set performv: aSelector : arguments]; }
...
@end
